New

Britain, Conn, a corporation of Connecticut Application November 8, 1938, Serial No. 239,426 2 Claims. (oi. l6-134) lVIy invention relates to a hinge.

It isan object of the invention to providean improved form of hinge for anti-frictionally carrying a door.

It is another object to provide an improved form of hinge relatively simple in construction and easy to apply and adjust and, in general, the object is to provide an improved form of door b nge.v

In the drawings which show, for illustrative purposes only, preferred forms of the invention- Fig. 1 is a fragmentary illustrative view of a door and door casing showing my improved hinges applied thereto;

Fig. 2 is a top .plan view of the upper hinge shown in Fig. 1;

Fig. 3 is a vertical sectional View through hinge parts shown in Fig. 2;

Fig. 4 is a vertical sectional view through hinge parts of the intermediate hinge of Fig. 1;

Fig. Sis a top plan view of the hinge shown in Fig. 4;

Fig. 6 is a top plan View of the bottom hinge shown in Fig. 1; and

Fig. 'l is a vertical sectional view through hing parts shown in Fig. 6.

In said drawings 5 indicates a door to be supported in the door casing, which includes a jamb 6 and lintel I. In the form shown the door is supported by an upper hinge 8 and lower hinge 9 In some cases only two hinges will be required.

. The top hinge 8 in its preferred form comprises a plate H, to be mortised into the underside of the lintel l. The plate I! has a lateral offset portion including a boss l2, having a bore i3 therein. The second hinge part includes a plate i l, to be mortised into and secured to the top edge of the door 5 and includes an offset plate with a boss l5 thereon. The boss l5 has a bore it therein, aligned with the bore l3 and, in the form shown, of larger diameter than the bore IS. A hinge pin l! fits in the bore I3 and is secured vtherein by suitable means, such as a screw l8 passing transversely through the pin l! and screwed into the boss, as indicated at I9. In order to anti-frictionally swing the door i top I may employ a needle bearing, including a bearing shell 26, carrying long thin rollers or so called needle bearings 2!, held in the shell by means of crimped-over end flanges 22-22, as will be understood. The inside diameter of the needle bearing is such as to permit the pin ll to fit snugly within it and form in effect an inner bearing race, so that when the door is swung the latter will be. anti-friotionally supported. The pin I! may beprovided with a screw slot 23 or the like, to facilitate registering the holes for the screw l8.

The intermediate hinge shown in Figs. 4 and 5 5 in the preferred form includes a plate 25, to be secured to the door jamb and is provided with an offset portion including a boss 25. A second hinge plate 2'3 to be secured to the side edge of the door includes an offset boss or knuckle 28. 10 One of the bosses, in this case the boss 26, is provided with a bore to snugly receive a hinge pin 29. The pin 29 is keyed against rotation in its bore, as by means of a key 30 and keyway 3i out in the bore of .the boss 26. Thus the pin 2%) is held against rotation but may be adjusted upwardly and downwardly. In the lower end of the bore, which is smaller than the upper or counterbored portion, there is a neck or tail piece 32, which is vertically supported by an adjusting screw 33, screwed into the lower end of the bore, whereby when it is desired to adjust the hinge, as will be later described, the adjusting screw 33 may be turned for moving the pin 29 upwardly or downwardly. A screw 34 may serve to close the lower end of the bore in the boss 26 merely 1 for the sake of appearance.

The upper boss 28 is provided with a bore aligned with the bore in the lower boss and of a larger. diameter, into which may be pressed a 30 needle bearing, including a sleeve and needle bearings 36 of the type heretofore described. The pin 29 extends upwardly and engages within the bore formed by the needle bearings 36, so

that the door during swinging is anti-frictionally 5 supported in a rotative direction. In order to support the downward thrust of the door the pin means 29 is made so as to constitute, in effect, a two-part pin means, one part being the pin 29 described and a second pin part or washer 31, in this case slightly smaller in diameter than the pin 2?) and resting in the upper end of the bore in the upper boss 28. The adjacent faces of the pin parts 29-43! are provided with raceways for anti-friction bearing members, such as balls 38. In the form illustrated the washer or upper pin part 3'! is held in place by means of a shouldered pin 39, tightly pressed into an axial hole in the pin 29, as illustrated. The washer 37 has a bore to loosely receive the shouldered portion of the 0' pin 39 and the head ti] on the pin is loosely received and housed in a counterbore in the washer 3'5. Thus the latter is loosely held relatively to the lower pin part 29 and yet is held suiliciently I securely to prevent the escape of the anti-fric- 5 er pin part 29 is non-rotatably carried by the boss 26, so that there is no tendency during opening and closing of the door to loosen the adjusting screw 33. The upper pin part 37 resting on the balls 38 supports the upper boss 28 and during opening and closing of the door the rotation will be between the two pin parts rather than between the upper pin part and the upper boss 28. Thus the door will be anti-frictionally supported both rotationally during swinging and vertically (when both anti-friction means are employed).

, In the form of lower hinge illustrated in Figs. 6 and 7 there is an angle plate 4-5, to be secured to the door jamb or floor or both, and the angle .plate has a bore for receiving the turned-down end 46 of a hinge pin 47, the shoulder of which may rest on top of the horizontal portion of the angle plate and be securely held against vertical movement and, due to a tight fit between the turned-down end 46 and its bore, also against rotative movement.

A second hinge plate 48 is adapted to be secured to the under side of the door and. has an ofiset boss or knuckle 69 having a downwardly opening bore in axial alignment with the pin 41. The bore is of sufiiciently large diameter to receive a needle bearing, including a shell 50 and needles 58 of the type heretofore described. The pin 41 forms the inner race of the needle hearing; The upper portion of the bore is of slightly smaller diameter and snugly receives a washer or upper pin part 52, which may be held to the pin part 41 in the manner heretofore described in connection with Fig. 4. Anti-friction bearing members, such as balls 53, are interposed between the two pin parts. The upperzpin part is designed to rotate within the bore and, in the form. shown, a washer 5d rests on top of the pin part 52 and is keyed by means of a tongue and key slot against rotation in the boss. Resting on top of the washer 54 is a lock washer 56 and an adjusting screw 51' in "the boss engages the lock washer.

Thus, when it is desired to adjust the door vertically the screw 51 may be turned so as to raise or lower the door. When the pin has been adjusted there is no tendency for the latter to Vibrate or work out of adjustment, since the washer 55 and lock washer 56 serve to prevent any rotative action of the pin 51 during operation of the door.

All three hinges have been shown as embodying means for swinging the door anti-frictionally, and two as embodying adjustable means for antifrictionally carrying the weight of the door. In many cases only one adjustable means need be employed and in some cases the needle bearings may be omitted.

While the invention has been described in considerable detail and preferred forms shown, it is to be understood that various changes may be made and that the various hinges may be used together or independently or in connection with other hinges, all within the scope of the invention as defined in the appended claims.

I claim:

1. In a floor type hinge, two hinge parts, one part being adapted to be seated in the floor, the other being adapted to be carried at the lower edge of a door, each part having an offset boss and each boss having a bore, a pin rigidly mounted in the boss of the lower hinge part, a bearing washer non-rotatably mounted in the bore of the other part but adjustable longitudinally therein, anti-friction devices between the upper end of said pin and the lower side of said bearing washer, and means in the upper end of the boss carried by the door for adjusting the longitudinal position of the bearing washer for the purpose described. I

2. In a floor type hinge, two hinge parts, one

part being adapted to be seated in the floor, the.

other being adapted to be carried at the lower edge of a door, each part having an oifset boss and each boss having a bore, a pin rigidly mounted in the boss of the lower hinge part, a bearing washer non-rotatably mounted in the bore of the other part but adjustable longitudinally therein, anti-friction devices between the pin and the adjacent walls of the washer and'bore in the other hinge part to take both the axial and lateral thrust of the latter, and means in the upper end of the boss carried by the door for adjusting the longitudinal position of the bearing washer for the purpose described.
